Nonpersistent message speed (NPMSPEED)

This attribute specifies the speed at which nonpersistent messages are to be sent.

Possible values are:

NORMAL: Nonpersistent messages on a channel are transferred within transactions.
FAST: Nonpersistent messages on a channel are not transferred within transactions.

The default is FAST. The advantage of this is that nonpersistent messages become available for retrieval far more quickly. The disadvantage is that because they are not part of a transaction, messages might be lost if there is a transmission failure or if the channel stops when the messages are in transit. See Safety of messages.

This attribute is valid for channel types of:

Sender
Server
Receiver
Requester
